Strange I didn't notice before but all of a sudden I have noticed that if I up the speed of my memory chips to 1600 (Which they support) . The bios only displays 4gb Instead of the 6gb that is installed... If I lower the memory speed to 1066... all 6gb is detected..

I have read various threads about this but I can't see much sense from them.
some ppl say the processor pins may be bent.. but the I7 doesn't have pins does it?

Anyway if the processor was faulty then surely the PC would crash all of the time (which it doesn't)

The system is very stable, that's why I can't understand why its not picking up the memory when the frequency is enabled to 1600 by using the MIT profile 1 on the gigabyte bios.

The strange thing is that I was sure it has been working before..

I don't think its a fault with the memory either, as when the frequency is at 1066 all 6gb are detected and I don't get any instability.. windows sees the 6gb..

Just a bit annoyed that I can't seem to figure out what I need to do to get all 3 triple channel sticks to run at 1600..
 
Just for the bings and googlers

Anyone who suggests that your processor is faulty please try this first:

take all memory modules out

Blow out the slots (I used compressed air)

Re seat the memory and make sure they are completely secure in the slots (Check the latches each side)

Job done..

Works now..
 
Yeah my first idea was to update the BIOS but it's already got the latest version according to the gigabyte update tool.. F1

It seems that this problem is quite common but so many people have so many different stories about it, some saying that the MB is broken, RMA everything but to be honest I don't believe anything is broken... normally these things have a simple solution.
 
Ok I have upped the QPI/VTT slightly to see if it is more stable at running at the 1600mhz speed.

Will let you know the results
 
Ok its stopped working after 1 wk

I have slightly increased the voltage again

see what happens now..

hopefully I won't cook the ram
 
Well the QTT voltage increases dont seem to do much. It last for a week and then goes back to 1066.

It's not a big deal though, just have to go into bios and save and exit and its back to 1600 again.

very strange.
 
I've updated to the Beta Bios.. Seems quite different and the speakers make some strange noises during post but its working so I'll see if it lasts longer than a week this time.
 
Yeah I know. It runs absolutely fine at lower speeds.
Its just that I wan't to explore all avenues before accepting defeat with this.

Its still working since I upgraded to the beta bios.. the current record is a week so I'll have to wait a few more days to find out if it worked or not.
 
It's still working, Its beaten the last record set.

I might be getting ahead of myself but I think its working since I upgraded the bios.
 
Consider it fixed..

Guess the beta bios did the trick.


I will only update this if anything else happens.

thanks for everyones input on this problem.
